An investigation of the hydraulic flight control system of a Boeing CH-47 Chinook helicopter using artificial intelligence techniques will be undertaken. Specifically, a knowledge based expert system will employ situation-action rules (production rules) to diagnose a failure and subsequently identify specific device(s) which caused that failure. Moreover, because the behavior of the system is directly responsive to the goals the system is directly attempting to achieve, the expert system's inference engine performs a backward-chaining process via a goal-driven control strategy. This strategy involves finding rules that demonstrate the hypothesis and then verifying the facts that enable the rule to work. The List Processing Language (LIPS) is used to facilitate data processing and symbolic logic expression manipulation. Keyword: Diagnostics.
